Answer:

It will take 5.33 years for the price of gas to reach $4.8.-

Step-by-step explanation:

Giving the following information:

Present value= $3.7

Future value= $4.8

Growth rate= 5%

<u>To calculate the time required to reach  $4.8, we need to use the following formula:</u>

<u></u>

n= ln(FV/PV) / ln(1+g)

n= ln(4.8 / 3.7) / ln(1.05)

n= 5.33

It will take 5.33 years for the price of gas to reach $4.8.-

Callie is starting a fruit basket business the largest basket has 30 pieces of fruit but the others have 12 pieces of fruit in e
Elis [28]

Answer:

In the first basket, Callie can make 15 apples, 10 oranges and 5 bananas.


In the second basket, she can make 12 apples, 8 oranges and 4 bananas and


in the third basket, she can make 9 apples, 6 oranges and 3 bananas.

Step-by-step explanation:

The largest basket contains 30 pieces of fruit. So, it contains


1/2 of 30 = 15 apples


1/3 of 30 = 10 oranges and


1/6 of 30 = 5 bananas.


The second and third baskets should contain at least 12 pieces and at most 30 pieces (since the largest basket contains 30 pieces). Also, the number should be divided by 2, 3 and 6. So, it must be a multiple of 6.


Clearly, the number of multiples of 6 between 12 and 30 are 18 and 24.


Hence, the second basket contains 24 pieces of fruits and it contains


1/2 of 24 = 12 apples


1/3 of 24 = 8 oranges and


1/6 of 24 = 4 bananas


The third basket contains 18 pieces of fruits and it contains


1/2 of 18 = 9 apples


1/3 of 18 = 6 oranges and


1/6 of 18 = 3 bananas.

The difference between the measures of two supplementary angles is 92. Find the measure of both angles
Sholpan [36]

supplementary angles add up to 180 degrees

x + y = 180

x - y = 92

---------------add

2x = 272

x = 272/2

x = 136 <=== this is one angle

x + y = 180

136 + y = 180

y = 180 - 136

y = 44 <=== this is ur other angle
